Purple Coin Omlet

About Purple Coin Comets: When you access a Galaxy while a Purple Coin comet is in orbit, you'll have to partake in a challenge to collect 100 purple coins in a specified part of the Galaxy. There are no checkpoints, so be careful, otherwise you'll have to collect all 100 coins again if you die. Also, a few of these challenges are timed and may have more than 150 purple coins total. In these cases, you do not have to collect them all; you still only need 100 total.

This level has numerous paths and can be quite confusing. The key is to launch from every Launch Star you come across - even the ones you encounter while flying through space. As long as you do, collecting all 100 coins is pretty straight forward.
